I only noticed that recently when I was watching, I think, OOGE for the first time. I'm still a bit confused about it, cause I could've sworn he used BdoubleO in Legendary, and the first OOGE came later, but maybe my memory is just not working.

I'm thinking more about the Mindcrack episodes. I started watching his Mindcrack at some point post-Legendary, pre-Spellbound, and he mentioned John regularly. It could easily have been playing with the nameless Etho that got him to switch back to game names, though.
